[0002] With multi-component mechanical linkage and precise control as its core design, it solves problems such as insufficient material positioning accuracy, poor clamping stability and interference from processing debris in the field of machining.

[0003] A search revealed existing technology (application number: CN117226564A), which describes "a precision machining positioning device with accurate positioning". This utility model includes columns, a workpiece table, positioning blocks, and a clamping assembly. Two columns are spaced apart on a base, and the workpiece table is movably connected between the two columns. Each end of the workpiece table has a first connecting part, and each of the two columns has a second connecting part. Multiple second connecting parts are arranged vertically, and the first connecting parts are used to connect with the second connecting parts. Two positioning blocks are slidably connected to the workpiece table, and the clamping assembly is used to confine the workpiece to be processed on the workpiece table.

[0004] However, while existing precision machining positioning devices with accurate positioning can achieve rapid positioning without the need for multiple manual adjustments to the workpiece position and can meet the processing requirements of precision components, they still have some shortcomings: existing technologies are structurally complex and lack positioning accuracy and stability. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a precision positioning device for machining.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a precision positioning device for machining, comprising: a base for supporting components; a lifting component including a slider one fixedly connected to one side of the base, and the slider one slidably connected to a support frame on one side of the base, and further including a guide post arranged at the bottom of the base for guiding; a vertical clamping component including a clamping block slidably connected to the base for horizontally clamping materials; a pushing component including a connecting block slidably connected to the base; a horizontal clamping component including a slider two disposed on the connecting block, and the slider two slidably connected to the base, and further including a clamping rod arranged on the slider two for vertically clamping materials; and an external expansion component arranged on one side of the base.

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example

[0029] like Figures 1 to 4 As shown, this embodiment provides a precision positioning device for machining, comprising: a base 1 for supporting components; a lifting component including a slider 4 fixedly connected to one side of the base 1 and slidably connected to a support frame on one side of the base 1, and a guide post 5 arranged at the bottom of the base 1 for guiding; a vertical clamping component including a clamping block 7 slidably connected to the base 1 for horizontally clamping materials; a pushing component including a connecting block 9 slidably connected to the base 1; a horizontal clamping component including a slider 10 disposed on the connecting block 9 and slidably connected to the base 1, and a clamping rod 15 arranged on the slider 10 for vertically clamping materials; and an external extension component arranged on one side of the base 1.

[0030] In this embodiment, the drive motor 2 drives the threaded rod 3 to raise and lower the slider 4, and the guide post 5 guides it; the threaded rod 6 drives the clamping block 7 to clamp laterally, the cylinder 8 pushes the connecting block 9 to clamp the clamping rod 15 vertically, and the vacuum cleaner 16 removes chips, thus achieving precise positioning of the material.

[0031] Specifically, the lifting assembly includes: a drive motor 2, which is arranged at the bottom of the support frame on one side of the base 1 to provide power; a threaded rod 3, which is rotatably connected to the support frame on one side of the base 1 and threadedly connected to a slider 4, and connected to the output shaft of the drive motor 2 through a coupling.

[0032] The drive motor 2 rotates and drives the threaded rod 3 to rotate through the coupling. Since the threaded rod 3 is threadedly connected to the slider 4, the slider 4 moves up and down in a straight line along the support frame, realizing the height adjustment of the lifting component with high precision.

[0033] Specifically, the vertical clamping assembly includes: a threaded rod 6, which is rotatably connected to the base 1, and the threads on its surface are symmetrically arranged, and it is threadedly connected to the clamping block 7.

[0034] As a preferred implementation, when the threaded rod 6 rotates, the symmetrically arranged threads drive the clamping blocks 7 to slide along the base 1 in opposite directions or in opposite directions, thereby achieving lateral clamping or loosening of the material and ensuring stable clamping. Example

[0035] Specifically, the actuation assembly includes a cylinder 8, which is disposed at the bottom of the base 1, and the top of the output shaft is welded to the connecting block 9.

[0036] It should be noted that the extension and retraction of the output shaft of cylinder 8 causes the connecting block 9 to slide on the base 1, providing power for the pushing component and realizing the position movement of the connecting block 9.

[0037] Specifically, the transverse clamping assembly includes: a first rotating shaft 11, rotatably connected to a second slider 10; a first connecting rod 13, rotatably connected to a base 1 via a third rotating shaft; a second rotating shaft 12, rotatably connected to the first connecting rod 13; and a second connecting rod 14, one end of which is connected to the first rotating shaft 11, and the other end of which is connected to the second rotating shaft 12.

[0038] As a preferred implementation, when the connecting block 9 drives the slider 10 to slide, the slider 10 drives the connecting rod 14 to move through the rotating shaft 11. The connecting rod 14 drives the connecting rod 13 to rotate around the rotating shaft 3 through the rotating shaft 12, ultimately causing the clamping rod 15 to move vertically, thereby achieving vertical clamping of the material. The structure is flexible. Example

[0039] Specifically, the external extension component includes a vacuum cleaner 16 for removing debris generated during drilling.

[0040] It should be noted that after the vacuum cleaner 16 is powered on, the internal motor runs and generates suction to suck up the debris produced during processing, keeping the work area clean and preventing the debris from affecting the processing accuracy.

[0041] Specifically, the clamping block 7 is made of rubber with a rough surface, making it less prone to slipping during clamping.

[0042] It should also be understood that by utilizing the elasticity of rubber and the friction of its rough surface, the contact friction between the material and the clamping material is increased, preventing the material from slipping and improving the stability of the clamping.

[0043] In use, the user places the material on the base 1. Depending on the size of the object, the user can adjust the height of the device. The drive motor 2 is activated, causing the threaded rod 3 to rotate. The slider 4, threaded onto the threaded rod 3, slides on a support frame on one side of the base 1. A guide post 5 is located at the bottom of the base 1 to guide its movement. When the user adjusts the height to the desired position, the cylinder 8 is activated. The output shaft of the cylinder 8 retracts, causing the connecting block 9 to move inward. The slider 10, located on the connecting block 9, moves inward along with the cylinder 13. The connecting rod 13 is rotatably connected inside the base 1, and the slider 10 and the connecting rod 13 are connected by the connecting rod 13. The connecting rod 14 is connected to the connecting rod 14, and the two ends of the connecting rod 14 are respectively provided with the first rotating shaft 11 and the second rotating shaft 12, which are rotatably connected to the second slider 10 and the first connecting rod 13. The movement of the second slider 10 drives the first connecting rod 13 to fold inward through the second connecting rod 14, thereby driving the other side to move inward together, thus completing the vertical clamping of the material. Then the user rotates the threaded rod 6. The threads on the upper surface of the threaded rod 6 are symmetrically arranged, thus driving the clamping block 7 to move in opposite directions to complete the lateral clamping of the material. At this time, the user can hold the welding gun to weld the material, or hold the hand gun to drill holes in the material. The vacuum cleaner 16 arranged on one side of the base 1 is used to clean the debris generated on the surface of the material after drilling.

[0044] It should be noted that all electrical components mentioned in this article are connected to an external main controller and 220V AC mains power. The main controller can be a conventional known device that can be controlled by a computer or other means. The detailed description of known functions and known components is omitted in the specific implementation of this disclosure. In order to ensure the compatibility of the device, the operating methods used are consistent with the parameters of commercially available instruments.

[0045] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
